Like others have said, Seekins/ Vortex PMR rings are definitely worth looking at!!!! Nearly all my rifle/scope combos wear them! Love them, very secure!!!! Idaho-5R
I went with the nightforce ultra lights, I only chose them because I was mounting a nightforce scope. If it wasn't a NF scope, I'd probably have used the warne rings and saved a bit of $$$. If you get the nightforce rings, you can get them for 10% off and free shipping from 1 shot gear, that's where I got mine and they were just under 150.00.
